@nikolgiorgos From my xp AMC works better if he is offensive minded than pulled back on mc. I have had few am-mc's and am-st's and they react better in offensive part of game, although sometimes it's individual.
Today I had league match where my amc got 6 in 4411 formation. He had blue arrow. Then I tested him without arrow in friendly and he got 7. Maybe it is usuall oscillation, but I believe that removed arrow had impact.
